I just installed Nextcloud 15 and tried to setup storage encryption with the default encryption module.
The admin manual says that there should be a field to set a recovery-key: https://docs.nextcloud.com/server/15/admin_manual/configuration_files/encryption_configuration.html#enabling-encryption
But there is none. A Github issue says that from NC13 on there is no such feature anymore: https://github.com/nextcloud/server/issues/8283
So what is correct?
